IMPROVEMEN'YI IN WATER-WHEELS.

Specification forming part of Letters Patent No. 132,298, dated October15, 1872.

top View, partly in section, of the same.

Similar letters of reference indicate corresponding parts.

The invention relates to a new construction of gate mechanism for awater-wheel; and consists in bracing the top of the cylindrical gate bya frame-Work which extends over the wheel, and in slottin g thestationary external chute-cylinder to admit the projecting arm from thegate to which the toothed segment for adjusting the gate is attached. Bythe Y use ofthis invention the gate-cylinder is braced and preventedfrom springing to one side or the other, and from consequently bearingagainst the wheel or chute-cylinder, or both, and hindering theoperation by excess of friction.

In the accompanying drawing, the letter A represents the water-Wheel; B,the gate-cylin- The wheel is mounted upon the shaft D, and has bucketsof suitable style and number. The gate-cylinder embraces the wheel, andis interposed between the same and the chute-cylinder. The openingsthrough the latter and through the gate-cylinder are, respectively,equal in number with the buckets of the wheel. The

cylinder B has a liange, a, at the upper edge overlapping the wheel, andarms b b extending from said flange to an inner ring, d, thaty of thecylinder C, and crosses at its outer end the toothed segment f. Apinion, whose teeth en gage into those of the segment, serves, whenvturned, to turn the gatecylinder, to enlarge or reduce the openings tothe Wheel. The pinion can be turned by suitable means. The step of theWheel may be made'vertically and horizontally adjustable to center andkeep the Wheel always in the desired position.

It is evident that in the upper bracing-frame of the gate-cylindertheiange al may be dispensed with if the arms b reach directly to thecylinder.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. rIhe gate-cylinder B, interposed between the wheel Aand chute-cylinder C, and braced on top by the frame b d., substantiallyas herein set forth.

2. The gate-cylinder, provided with the projecting arm e and segment f,and combined .with the chute-cylinder C, which is slotted to admit thearm e, substantially as herein set forth.
